Abstract
Apparatus for warming coffee or other beverage includes a warmer plate on which a vessel holding the beverage to be warmed is set, a heater for heating the warmer plate, circuitry for controlling the time the warmer plate is in a heating condition and a weight sensitive switch for enabling the circuitry only when a vessel of pre-determined weight is on the warmer plate. The circuitry further includes components for reinitializing the time the warmer plate is in a heating condition after a vessel is removed from the warmer plate under predetermined time conditions and then replaced thereon.
